Indeed, the DocxFormatProvider that is shipped with RadRichTextBox is located in the Telerik.Windows.Documents.FormatProviders.OpenXml.dll. Note that in order to be able to import/export DOCX files a reference to the Telerik.Windows.Zip assembly is required as well. More information on the topic is available in the Assembly References section.

I hope this helps.
